The Coppock curve is a long-term price momentum indicator used primarily to recognize major bottoms in the stock market. Most technical market analysts consider the Coppock curve to be an excellent tool for discriminating between bear market rallies and true bottoms in the stock market.
Elementary calcium reacts with water. Calcium compounds are more or less water soluble. Calcium carbonate has a solubility of 14 mg/L, which is multiplied by a factor five in presence of carbon dioxide. Calcium phosphate solubility is 20 mg/L, and that of calcium fluoride is 16 mg/L.
The hydroxides of the alkali metals, lithium, sodium, potassium, rubidium, and cesium, are the strongest bases and the most stable and most soluble of the hydroxides. Sodium hydroxide, NaOH, also known as caustic soda or lye, is of great industrial importance. Calcium, barium, and strontiumâall alkaline earth metalsâform soluble hydroxides that are strong bases but are less stable than the alkali hydroxides. Of these, calcium hydroxide, Ca(OH)2, commonly known as slaked lime, is the most common. With the exception of thallium hydroxide (TlOH), the hydroxides of other metals, such as magnesium, iron, bismuth, nickel, cobalt, and copper, are only sparingly soluble in water but neutralize acids.
